My invention relates to an improvement parts as will be more fully hereinafter,

pointed out. I When handling a patient on an operating table it is often most important to be able to turn the patient from side to side and raise and lower the patient and also certain portions of the body and to move the table but have it rigidly secured in a fixed position when desired. These can all be done quickly, easily and without disturbin the patient on my operating table an the patient may by means of my table be placed in as low or as higha position or in any particular position as may be desired by the doctor operating with my table.

Refering to the drawings, Figure 1 is a side elevation of m device. 'Figure 2 is an end view looking in atthe same from the left hand end of Figure 1. Figures 3 to 10 inclusive are details of the structure of my device.

In the drawings 11 is a pedestal having four legs 1201i each of which'is a wheel or caster 13 and two. of these are fitted with brake or stop members 14 of usual construction adapted to be operated by foot.

A vertical supporting rod 15 is mounted in said base 11 under vertical control of an oil pump (not shown) of usual construction operated by means of a foot control lever 24 and an upper supporting rod 15 is pivoted a cylindrical T member 17, having an internal threading 18 and a triangular opening 19 in a tail piece 20, is givotally secured by a pin 21 which loosely ts triangular openmg 19. A cross rod 22 has a central portion 23 which is a worm gear adapted to engage and turn through the internal threading 18, of T member 17.

Frame 25 has cross bars 26 and 27 both 45 of which are mounted over the supporting rod 15 and cross rod 22 is mounted in bearings 28 in" said frame 25 and has a crank and handle 29 at one end.

Shafts 30 and 31 are mounted in the frame 25 at the opposite lower ends so as to turn freely therein by means of wheels 32 and 33 rigidly secured thereto. Said shafts 30 and 31 pass through gear boxes 34 and 36 respectively, of usual construction, operating gear rods and 37 respectively in the on 15 at 16. At the upper end of said rod 15*" well known manner. Said gear rods 35 and 37 have respectlvely pivoted at their upper ends table topl members 38 and 39 which are hinged toget er by a rod 40 which is encased by but turns readily in a cylindrical hinge member 41. A foot table top member 42 1s hinged to 39 by rod 43 and cylindrical h nge member 44 and a head rest 45 is h nged to 38 by rod 46 and hangers 46 rigidly secured to top 38. An adjustable ratchet supporting are 47 is pivoted at 48' to a forked member 49 which is rigidly secured to table top member 38. A forked lug 51 secured to the bottom of said head rest 45 has a pin 52 adapted to be enga ed by the ratchet teeth of the are 47. A rate et supporting hai is secured in a manner similar to are 47 to top member 39 to permit hand ad ustments oftable top member 42.

Track bars 38", 39 and 42" are rigidly set 75 011? on each side respectivel of the top members 38, 39 and 42'. On t ese bars 38, 39 and 42* are mounted slidable bracket members 53 having slots 54 cylindrical borings 55 and sliding clamp members 56. Shoulder brace members 57 and side brace members 58 are adapted to be mounted. in said slots 54 of the bracket members 53 and anaesthetizer arch 59 and heel supporter 60 are adapted to be mounted in cylindrical bor- 1ngs 55. Clamping brackets 61 are rigidly secured at 62 to lower extension members 63 of top member 42 and stirrups 64 are adapted to be clamped therein by means of clamping screws 65 and handles66. A foot support or extension member 67 is mounted on track bars 42 by means of slidabl'e brackets 68 having sliding clamp members 69 and cross slots 70 and 71 engaged by legs 72 of extension member 67 held in position by means of set screw 73. Socket bracket members 74 are mounted on track bars 39 by means of the bracket members registering over the track bars'39 and also by means of set screws 75. 10'0 The operation of mydevice is as follows:

The table is adjusted'to the height required by the doctor-usin' it by means of the foot control lever 24 w ereby the operation of the oil pump controlled by said foot control lever 24 will raise or lower the supporting rod 15 and the frame 25 andto sections carriedthereby. The table may t ere- -.by be lowered to a position to suit the height of the doctor so that a very short man may to ermit the table to assume the lowest-pos sib e osition, the lower part ofthe pedestal 11 being just clear of the floor. The patient.

may then be placed upon the table with the extension member 67 in the position shown in Figure 10 in dotted outline, thereby increasing the length of the table where the case so requires. The head rest 45' is in my.

I device so constructed as to permit the an- "sired.

aesthetizer to rest his arms on this member while. administering the anaesthetic so as to do this in a much more eflicient manner than has been possible heretofore, The shoulder brac'e members 57 can be adjusted to the position desired and the arch 59 will. be moved accordingly. The feet of the patient can be then adjusted in heel support 60 or in stirrup members 64 as may be desired or the legs of the patient may be strapped into socket bracket members 74. The side brace members 58 may be placed in position as found best adapted to the position of the patient. The operator can at any time, before or during the operation, change the p sition of the top members 38 and 39 by mians of the wheels 32 and 33 tilting them as may be required and they will move according to such movement of the wheels 32 and 33 being hinged together as described and because 'of the construction of the hinge it is impossible for the body of the patient to be pinched. In turning the wheels 32 and 33 to the right or left to raise or'lower the top members 38 and 39 the gearboxes transfer the motion through thesh'afts 30 and 31 and thereby raisin and lowering the gear rods 35 and 37 respectively. Inasmuch as the cylindrical bearings 41 are outside of the inside hinge rod 40 perfect protection is furnished to the patient. The head rest 45 may be changed as may be required by lifting the are 47 and raising or lowering the head rest until the notch desired in 47 is registered on the pin 52. Similarly the foot table top member 42 may be raised or lowered manually throu h the use of the ratchet supporting bar 50 which will lock it in the position de- The entire frame 25 carrying the top and the parts mounted thereon may. be

tilted to one side or the other to the position desired by the turning of the crank 29 p which will causetne central ortion 23 to ossible in my construc- .in movement of the cylindrical member on said pin 21.

In preparing the table for operation the brake members 14 will be thrown down to lock the table in position on the floor against accidental movement after the table has first been adjusted'in the position desired to use it during the o eration.
